In jsonb_plpython.c, suppress warning message from gcc 10.
Very recent gcc complains that PLyObject_ToJsonbValue could returna pointer to a local variable. I think it's wrong; but the codingis fragile enough, and the savings of one palloc() minimal enough,that it seems better to just do a palloc() all the time. (My otheridea of tweaking the if-condition doesn't suppress the warning.)Back-patch to v11 where this code was introduced.Discussion:https://postgr.es/m/21547.1580170366@sss.pgh.pa.us
